问题描述
我正在尝试在我的本地tomcat上运行简单的Web应用程序 - 该应用程序基本上是您在IntelliJ中创建Web应用程序时所获得的，因此目录结构是vanilla。我实际上没有触及index.jsp或web.xml。
I am trying to run simple web app on my local tomcat - the app is basically what you get when you crate "web application" in IntelliJ, so the directory structure is "vanilla". I am literally not touching either index.jsp or web.xml.
我在Maven下这样做，所以这是我的pom文件：
I am doing this under Maven, so here is my pom file:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.testapps</groupId>
<artifactId>Test_App_1</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>war</packaging>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<webXml>web\WEB-INF\web.xml</webXml>
</configuration>
</plugin>
</plugins>
</build>
</project>
所以这就是我在做的事情：
So here is what I am doing:
- 在maven下构建这个项目：
mvn compile install - 我正在复制app_name.war文件从我的本地仓库进入tomcat webapps目录
- 运行tomcat：
catalina start - I我可以看到我的应用程序在管理器中，但是当我尝试输入它时（或者当我输入）发生404错误。
- Building this "project" under maven:
mvn compile install - I am copying app_name.war file from my local repo into tomcat webapps directory
- Running tomcat:
catalina start - I can see that my application IS THERE in manager, but when I try to enter it (or when I just type http://localhost:8080/app_name) the 404 error occurs.
我做错了什么？我不了解一些基本概念或遗漏一些基本的东西？我应该以某种方式明确地将这个index.jsp包含到我的.war文件中吗？如果是这样，我如何在IntelliJ下执行此操作？我真的只是试图运行这个vanilla应用程序而且我的印象是，index.jsp应该是这个.war文件的一部分，它应该自动显示。当我手动执行此操作时，我将在webapps文件夹中创建一些TestDirectory，复制相同的index.jsp文件并将其放在该目录中，然后访问它 - 它会自动显示这个index.jsp文件。
What I am doing wrong? Am I not understanding some basic concept or missing some basic thing? Should I somehow explicitly INCLUDE this index.jsp into my .war file somehow? If so, how do I do that under IntelliJ? I am literally just trying to run this "vanilla" application and I am under the impression, that index.jsp should be a part of this .war file and it should be displayed "automatically". And when I do it manually, so I will just create some TestDirectory in webapps folder, copy the same index.jsp file and place it in that directory, and then acces it http://localhost:8080/TestDirectory - it automatically displays this index.jsp file as it should.
抱歉对于，可能，愚蠢的问题，我真的很新，我找不到解决方案。
Sorry for, probably, dumb question, I am really new to this and I couldn't find a solution.
推荐答案
删除maven- war-plugin，在服务器上构建和重新部署并测试之后
remove maven-war-plugin ,after that build and redeploy and test in server
